Hoops sorry: please read at the first one below :

I came in here just to say two things as a "user"
- the punycode thing seems OK but the DNS aspects are
  inadequate
- the text you produced is not easily understandable.
I was said to be a troll for the second point. May be
could we also look at the (second) first one?

"probably" necessary ???
At this date, this rises a lot of question.
All I found was a very early commitment to that in the process.
I did not read everythng yet.
Any reason why it is "certainly" necessary?
(a part from obvious non technical reasons)

You point is accepted. But to say that applying ToASCII to
a valid ASCII name is equivalent to do nothing does not
removes the need to use ToASCII, but helps understanding
that this is what actually happens. The way it is written leaves
many questions open.
